As I understand, with most Li-ion cells, the colder the cell, the less
charge it will take on. Correct ?
But what happens if a warm battery is charged and then cools off ? It
still has all its kWh, right ? And further, the temperature of the
battery does not affect how many kWh you can get *out*
Peri,
It is the *speed*, not the *capacity* that suffers in very cold weather.
Think of it as ions moving sluggish through the lattice that makes up
the active material.
The colder, the more sluggish.
Forcing too much current into this can even cause faults to develop,
which *are* reducing the capa
Well, then, why is the range substantially less in cold weather ? The
charger nor the battery don't know the discharge rate while charging.
I understand that charging needs to be slower. But how does that affect
capacity ?
As a matter of example, during 20F weather last december, I was gettin
Instead of intercalating, the ions end up plating the surface of the anode.
Charging in freezing temps can cause plating, which reduces battery capacity
and increases Resistance

I'm not sure about the newer models, but definitely no battery heater
(or cooler) for the 2011 model.
Anyway, no one has yet addressed whether my hypothesis is true or not:
if you charge while the battery is warm, it will still be able to
deliver all the kWh even when the battery has become co
